Currently contemplating Philistines I have thought of the following. Like many civilizations which faded which already exist in Civ, I must try to imagine what post-Ancient units would look like. I would imagine that as an Aegean people they would eventually come under Greek influence with trade. Being near Mesopotamia, they would also fall under influence from there as well. So imagine the units would reflect this more, while keeping a Philistine feel. I will think of something for my civ. As for the leaderhead? Any suggestions? Who would be a good base.
